Muhinduzi: Reba uwo mwashakanye Ibirahure byose
Amategeko y'ingenzi y'iboneza:
Ikirahuri gisanzwe (ubugari ≤ metero 1.8 × uburebure ≤ 1,2 metero)
Ibipapuro bibiri kuri buri kirahure (hejuru / hepfo cyangwa kuruhande) birahagije kubice byumuyaga muke.
Urugero:
Uburebure bwa metero 1,2 z'uburebure → busaba pin 2.
Ikirahure kinini (ubugari> metero 1.8 cyangwa uburebure> metero 1,2)
Ibipapuro bitatu kugeza kuri bine kuri buri kirahure birakenewe kugirango ukwirakwize umuyaga / ingaruka.
Ibice by'imfuruka mubisanzwe bisaba imbaraga ziyongera.
Ibintu by'ingenzi:
Imizigo yumuyaga (ASCE 7): Ahantu h’umuyaga / hejuru yumuyaga bisaba 50% byinshi (urugero, pin 3 kubirahuri bya metero 1.5 z'ubugari).
Ubunini bw'ikirahure: ikirahuri cya 15mm cyemerera umwanya munini kuruta ikirahure cya 12mm.
Urwego rwibikoresho: ASTM F2090 ibyuma byemewe bisobanura umwanya ntarengwa kuri buri gice (mubisanzwe metero 1.2-1.8).
Ingaruka zubuhanga budahagije:
Ihinduka ryibikoresho → guhangayikishwa nikirahure.
Gucomeka ibirenze → guhuza kunanirwa ikirahure cyangwa inkingi.
Kutubahiriza code ya pisine (IBC 1607.7, AS 1926.1).
